Dryer runs but does not heat (electric Whirlpool dryer, no error code displayed)

Safety First: Unplug the dryer. Heating components can remain hot after use.

• Verify power: For electric models, confirm 240 VAC at the outlet and terminal block. If only 120 VAC is present, see L2-related troubleshooting.
• Access heater assembly: Remove the rear panel to access the heater housing and thermostats.
• Check thermal cutoff and high-limit: With wires disconnected, test the thermal cutoff and high-limit thermostat for continuity using a multimeter. Replace any open components with Whirlpool-approved kits (often sold as a pair).
• Test heating element: Disconnect the element leads and measure resistance across the terminals. An open reading indicates a failed element.
• Inspect wiring: Look for burnt or loose connections at the heater and thermostats. Repair or replace as needed.
• Replace faulty parts: Install a new heating element or thermostat kit as indicated by testing. Ensure all mounting screws are tight and wiring is routed correctly.
• Reassemble and test: Reinstall the rear panel, restore power, and run a timed dry cycle to confirm proper heating.
